уведомляет librdmacm об асинхронном событии (Notifies the librdmacm of an asynchronous event.)
Имя (Name)
rdma_notify - Notifies the librdmacm of an asynchronous event.
Синопсис (Synopsis)
#include <rdma/rdma_cma.h>
int rdma_notify (struct rdma_cm_id *id, enum ibv_event_type
event);
Аргументы (Arguments)
id RDMA identifier.
event Asynchronous event.
Описание (Description)
Used to notify the librdmacm of asynchronous events that have
occurred on a QP associated with the rdma_cm_id.
Возвращаемое значение (Return value)
Returns 0 on success, or -1 on error. If an error occurs, errno
will be set to indicate the failure reason. If errno is set to
EISCONN (transport endpoint is already connected), this indicates
that the the underlying communication manager established the
connection before the call to rdma_notify could be processed. In
this case, the error may safely be ignored.
Примечание (Note)
Asynchronous events that occur on a QP are reported through the
user's device event handler. This routine is used to notify the
librdmacm of communication events. In most cases, use of this
routine is not necessary, however if connection establishment is
done out of band (such as done through Infiniband), it's possible
to receive data on a QP that is not yet considered connected.
This routine forces the connection into an established state in
this case in order to handle the rare situation where the
connection never forms on its own. Calling this routine ensures
the delivery of the RDMA_CM_EVENT_ESTABLISHED event to the
application. Events that should be reported to the CM are:
IB_EVENT_COMM_EST.
